BACKGROUND: Flare-ups of the hips are among the most feared and disabling complications of fibrodysplasia ossificans progressiva (FOP) and are poorly understood. In order to better understand the nature of hip flare-ups in FOP, we evaluated 25 consecutive individuals with classic FOP (14 males, 11 females; 3-56years old, median age, 17years old) who presented with acute unilateral hip pain. RESULTS: All 25 individuals were suspected of having a flare-up of the hip based on clinical history and a favorable response to a four day course of high-dose oral prednisone...

INTRODUCTION: Managing fractures of distal tibia is still a subject of debate for orthopaedic surgeons in terms of both, reduction and fixation. Subcutaneous location and soft tissue anatomy predisposes it to angular and rotational instability as well as other bony and soft tissue complexities. Minimally invasive plating offers many advantages over conventional open techniques. It causes minimal soft tissue dissection and surgical trauma to the bone. Minimally invasive plate osteosynthesis(MIPO) maintains biological configuration of distal tibia and fracture hematoma and also provides a construct, which is biomechanically more stable...

BACKGROUND & OBJECTIVE: Fractures of the distal radius are common with a variable prognosis in case of intra articular extension. The available options include Plaster, External fixation, Prefabricated Splintage using Ligamentotaxis, K-wire fixation, and open reduction internal fixation with T-plate without an as yet clear advantage of one over the others. If these fractures are allowed to collapse, radial shortening, angulation and articular incongruity may cause permanent deformity and loss of function...

Strontium ranelate (SrRan) is a drug usually prescribed to treat osteoporosis, with proven effects of decreasing the risk of fractures and an indication of reducing the progression of osteoarthritis (OA). This study aimed to investigate the effects of SrRan as either a prophylactic or a treatment drug, using an OA rat model to assess pain behavior. A monoiodoacetate (MIA)-induced knee joint OA model in Wistar rats was used. Thirty Wistar rats (both sexes, 60 days old) were distributed in five groups of 6 rats each: the control group, that received no intervention; a prophylactic group, that received oral administration of 25 mg·kg-1·day-1 of SrRan for 28 days before induction of OA; a group treated with 25 mg·kg-1·day-1 of SrRan for 28 days after OA induction; a group treated with 50 mg·kg-1·day-1 during 28 days after OA induction; and a group that received oral saline for 28 days after induction...

BACKGROUND: Calcaneum is the most commonly fractured tarsal bone. The optimal treatment for displaced calcaneus fractures involving the posterior facet is surgical. The extensile lateral approach is commonly preferred because it provides sufficient exposure of the subtalar facet. However, this technique has the risk of complications such as wound necrosis and sural nerve injury. Various minimally invasive approaches, such as sinus tarsi approach, limited posterior approach, and percutaneous approach, have been introduced to reduce possible complications...

BACKGROUND: The optimal fixation strategy for unstable pediatric tibia fractures is unclear with some favoring elastic intramedullary nails (EIN) and others favoring plate and screws [open reduction internal fixation (ORIF)]. The purpose of this study was to compare outcomes and complications of skeletally immature patients undergoing surgical stabilization of the tibia with either EIN or ORIF. METHODS: A retrospective review was performed on all patients undergoing EIN or ORIF of a diaphyseal fracture at a single pediatric level I trauma center between 2010 and 2016...

BACKGROUND: We compared 3 surgical approaches to the MP joint: a dorsal extensor tendon-splitting approach, a dorsal extensor tendon-reflecting parasagittal approach, and the volar A1 pulley approach. We quantitatively compared each of these approaches by measuring the amount of articular cartilage exposed on the base of the proximal phalanx. We hypothesize that visualization of the articular cartilage of the proximal phalangeal base is enhanced with the volar approach. METHODS: The MP joints of the 32 available digits were randomly assigned to 1 of 3 surgical approaches: extensor tendon splitting (A), extensor tendon reflecting (B), or volar approach (C)...

BACKGROUND: Lysyl oxidase like-2 (LOXL2) is a copper-dependent amine oxidase. Our previous studies showed that LOXL2 is elevated during mouse fracture healing. The goal of this study was to evaluate the potential of LOXL2 to act as an anabolic agent in cartilage affected by osteoarthritis (OA). METHODS: LOXL2 was visualized in tissues from human knee and hip joints and temporomandibular joints (TMJ) by immunofluorescence. The activity of LOXL2 in human articular and TMJ chondrocytes was assessed by cell-based assays, microarray analysis, and RT-qPCR, and LOXL2-mediated activation of NF-κB and extracellular signal-related kinase (ERK) signaling pathways was measured by western blotting...

The assessment of a patient with chronic hip pain can be challenging. The differential diagnosis of intra-articular pathology causing hip pain can be diverse. These includes conditions such as osteoarthritis, fracture, and avascular necrosis, synovitis, loose bodies, labral tears, articular pathology and, femoro-acetabular impingement. Magnetic resonance imaging (MRI) arthrography of the hip has been widely used now for diagnosis of articular pathology of the hip. A retrospective analysis of 113 patients who had MRI arthrogram and who underwent hip arthroscopy was included in the study...

A 24-year-old woman fell while ice climbing and landed on her left foot. Radiographs were taken and read as noncontributory. Eight days after the injury, the patient was still unable to bear weight due to significant pain, so she self-referred to physical therapy. Following evaluation, she was referred to primary care for further imaging to rule out fracture. The physician ordered magnetic resonance imaging, which revealed a left mildly displaced fracture of the intra-articular lateral process of the talus...

BACKGROUND: We present a classification system that progresses in severity, indicates the pathomechanics that cause the fracture and therefore guides the surgeon to what fixation will be necessary by which approach. METHODS: The primary posterior malleolar fracture fragments were characterized into 3 groups. A type 1 fracture was described as a small extra-articular posterior malleolar primary fragment. Type 2 fractures consisted of a primary fragment of the posterolateral triangle of the tibia (Volkmann area)...
